Wu Jiang, Centers for Disease Control and Prevention
  Purpose
An observational study will be performed in subjects aged 3-65 years old to describe the dynamic changes of cellular immunity after vaccination of hepatitis B vaccine, and to find out the expression levels of Th9 cells and IL9 in subjects with different response to the primary immunization (3 single -dose injunctions).

Condition
Hepatitis B

Study Type: Observational
Study Design: Observational Model: Case Control
Official Title: Effect of the Expression Level of Th9 Cells and IL-9 In Poor/Non-responsiveness to Hepatitis B Vaccination

Estimated Enrollment: 94
Study Start Date: August 2011
Estimated Study Completion Date: May 2012
Estimated Primary Completion Date: April 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts
the value of anti-HBs =0 mIU/ml
Recent serological testing result show HBsAg, HBeAg, anti-HBe, anti-HBc, HBV DNA and Pre-S1 should be negative. had vaccinated hepatitis B vaccine and the value of anti-HBs be zero.
the value of anti-HBs≤5mIU/ml
Recent serological testing result show HBsAg, HBeAg, anti-HBe, anti-HBc, HBV DNA and Pre-S1 should be negative. had vaccinated hepatitis B vaccine and the value of anti-HBs≤5mIU/ml.
5mIU≤anti-HBs≤10mIU/ml
Recent serological testing result show HBsAg, HBeAg, anti-HBe, anti-HBc, HBV DNA and Pre-S1 should be negative. had vaccinated hepatitis B vaccine and the value of 5mIU≤anti-HBs≤10mIU
anti-HBs≥1000mIU
Recent serological testing result show HBsAg, HBeAg, anti-HBe, anti-HBc, HBV DNA and Pre-S1 should be negative. had vaccinated hepatitis B vaccine and the value of anti-HBs≥1000mIU.

Detailed Description:
This study selected 74 volunteers which had the hepatitis B vaccine (immunization programs 0,1,6) , anti-HBs≤10mIU as the research subjects, and choose 20 volunteers which anti-HBs≥1000mIU as the control group, revaccination the groups according to the normal immunization programs, then the blood samples would be collected at 7th day, separate the PBMC and detect the expression levels of Th9 cells and IL9 by FCM, trying to find out the effects of Th9 and IL9 of non/poor -responsiveness subjects to hepatitis B.
